Description

【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、金属帯材と合成樹脂フィルムとの誘導加熱
融着方法に関するものである。
〔従来の技術およびその問題点〕
従来、金属帯材と合成樹脂フィルムとの貼合わせ法とし
ては、押出し法あるいはフィルム貼合わせ法などが知ら
れているが、その何れの方法にも高温融着に伴なう樹脂
の酸化が生じたり、また金属帯材に対する両面同時融着
が不可能であるなどの問題点があった。
例えば押出し法にて積層品を作る場合は、樹脂の溶融温
度が非常に高いため樹脂か酸化されてしまい、熱接着力
の低下、酸化臭の大きいことが欠陥である。
また、フィルム貼合わせ法は、接着剤を用いずに加熱ロ
ールで熱融着する方法であるが、この方法では一般に強
い貼合せ強度を得る為には予備加熱と後加熱を要する。
このため、予備加熱にて金属帯材を加熱してからフィル
ムを熱圧着し、さらに後加熱を施こすのであるが、この
後加熱工程において樹脂の酸化が起り、押出し法におけ
ると同様、熱接着力の低下、酸化臭が残るなどの問題が
あった。才だ、後加熱ゾーンが非常に長いので生産性が
低いという問題もあった。
そこで、この発明は、金属帯材と合成樹脂フィルムの貼
合わせ法における上記の問題点を解消し、しかも金属帯
材の両面に合成樹脂フィルムを同時に貼合わす方法を提
供しようとするものである。
〔問題点を解決するための手段〕
この発明、金属帯材と合成樹脂フィルム□を重ね合わせ
た後、この金属帯材と合成樹脂フィルムとを電磁誘導コ
イル内□を通過させて金属帯材面に対して磁束を垂直方
向に透過せしめ、金属帯材内に発生する渦電流によって
金属帯材を加熱し、その熱によって合成樹脂フィルムを
金属帯材に連続的に融着させるようにしたものである。
〔作　用〕
上記のように、加熱源として誘導加熱装置を用いること
により、加熱が金属帯材内部から起って合成樹脂フィル
ムと金属帯材の界面で樹脂が溶融し、合成樹脂フィルム
が金属帯材に融着するのである。
この場合、金鴨帯材と合成樹脂フィルムとを、電磁誘導
コイル門を通過させることにより、金属帯材の両面に電
磁誘導コイルが位置して磁束が金属帯材面に対して垂直
の方向に透過するので、渦電流が金属帯材の全中に亘っ
て流れ、金属帯材が均一に加熱されるのである。
〔実施例〕
゛　以下、この発明の実施例を添付図面に基づいて説明
する。
Ａは金属帯材、Ｂは合成樹脂フィルムであり、その両者
は相互の融着を完全にするために貼合面をコロナ処理装
置５，５および６の通過によってコロナ処理し、圧着ロ
ール２によって合成樹脂フィルム−金属帯材−合成樹脂
フィルムを積層させる。
次いで、積層品Ｃを誘導加熱装置１に送り、電磁誘導コ
イル１０内を通過せしめる。即ち、誘導コイル１０が積
層品Ｃの両面に配置された状態で積層品Ｃを通過させる
のである。これにより、磁束が金属帯材Ａ面に対して垂
直の方向に透過され、渦電流が金属帯材の全中に亘って
流れる。従って、電磁誘導コイル１０内を約０．１〜１
．０秒間通過させることにより、金属帯１−ＪＡが１２
０〜１７０℃に加熱され、合成樹脂フィルムＢと金属帯
ＩＪＡとの界面で合成樹脂フィルムＢが溶融し、合成樹
脂フィルムＢが金属帯ＩＡに融着する。
このようにして金属帯材Ａの両面に合成樹脂フィルムＢ
が熱融着された積層品は、冷却室３に送られ、冷却空気
によって合成樹脂の融点以下に冷却された後、冷却ドラ
ム４、冷却ロール８に導かれてさらに冷却され、その後
に巻取ロール９に巻取られる。。
上記誘導加熱装置１としては、誘導コイル１０が金属帯
材の両面側に位置する形のものであれはよいが、金属帯
ＩＡの中方向の均一処理をより有効にならしめるために
、不出願人においてすでに出願中のものを用いることが
望ましい。
上記金属帯ＩＡとしては、アルミニウム又はアルミニウ
ム合金、銅、スチールなとの板状、或し１は箔が用いら
れ、熱融着合成樹脂フィルムＢとしてはポリエチレン、
ポリプロピレン、ポリ塩化ビニル、ポリ塩化ビニリデン
、エチレン−酢酸ビニル共重合物、ポリエステル、ナイ
ロンなどカイ適当である。この合成樹脂フィルムは、積
層品の使用目的、金属帯材Ａの種類に応じて適宜組合わ
される。
また、金属帯ｉＡおよび合成樹脂フィルムＢに対するコ
ロナ処理は、両者の熱融着をより向上させるためのもの
であり、図面では両者ともこの処理を施すものについて
示したが、必ずしもこれに限定されるものではな（、例
えば金属帯材Ａとして軟質アルミニウム箔を用いる場合
などはこの処理を施こさずとも十分に合成樹脂フィルム
Ｂとの熱触着性は得られるのである。
従って、この処理も使用する金属帯ＩＡおよび合成樹脂
フィルムＢの組合せに応じて適宜実施すれは良い。
上記実施例においては、金属帯ＩＡに対し合成樹脂フィ
ルムＢを両面同時融着することについて詳述したが、こ
の発明の方法ｉｔこれに限らす片面融着にも適用しうろ
ことはいうまでもない。また、この発明の方法は、従来
のフィルム貼合わせ法における予備加熱で金属帯材の片
面に合成樹脂フィルムを圧着したものに対する後加熱に
代えて採用することも出来る。
この発明の方法で得られる積Ｆｅｂ製品はアルミニウム
容器、およびその蓋材、ケーブルシース用、各種食品包
装用など広い用途に対して非常に有用である。
次に、この発明の方法を史に詳細に説明するために、具
体的な実施例を示す。なおこの実施例は何ら不発明を限
定するものではない。
実施例１ 軟質アルミニウム箔（５０μＸ５００ｍｍ幅）と、前処
理として軟質アルミニウム箔との融着面にコロナ処理を
施こした低密度ポリエチレンフィルム（３０μＸ５１０
１１１ＩＩ１幅）とを、圧着ロールを通過させて積層し
たのち、これを６０ｍ／分の速度で発振出力２３０ｋＷ
（２４５，０ＶＸ９３．９Ａ）、発振周波数１．８に七
の誘導加熱装置内をアルミニウム箔の温度１６０℃にて
通過せしめてアルミニウム箔に樹脂フィルムを融着させ
、その後冷却室にて冷却空気を吹きつけ、積層した樹脂
表面温度を１１０℃附近まで下げたのち、冷却ドラム、
冷却ロールを通し、アルミニウム箔片面にポリエチレン
フィルムラ融着せる積層製品を得た。
この積層品には樹脂の酸化県は殆んとなく、ポリエチレ
ンフィルムとアルミニウム箔との剥離強度は４２０！ｉ
’／１５馴幅〔剥離速度２００ｍｍ／ｍｍ、Ｔ−剥離〕
を示し、同じアルミニウム箔と低密度ポリエチレンフィ
ルムによる従来の押出し法にて得た積層品の剥離強度３
００〜３２０グ／１５＋ｎｍ　幅に比し大きな性能の向
上が認められた。
実施例２ 両面をコロナ放電処理した軟質アルミニウム箔（２００
μＸ６００＋＋ｌｌ＋１幅）と、同様にしてアルミニウ
ム箔との貼合面をコロナ放電処理したエチレン−酢酸ビ
ニル共重合体のフィルムとを圧着ロールニて積層したの
ち、これを４５ｍ／分の速度で発振出力９１．０ＫＷ（
４４２，３ＶＸ２０５．８Ａ）、発振周波数１，２ＫＨ
ｚの誘導加熱装置内をアルミニウム箔の温度１６０℃に
て通過せしめてアルミニウム箔の両面にフィルムを融着
させ、次いで冷却室内で冷却空気により積層した樹脂フ
ィルムの表面温度を１４０℃まで冷却したのち、冷却ド
ラム、冷却ロールを経てアルミニウム箔の両面にエチレ
ン−酢酸ビニル共重合体フィルムを融着せる積層製品を
得た。
このもののフィルムとアルミニウム箔の剥離強度は４５
０〜５００５’／１５ｍｍ幅（剥離速度２００ｍｍ／ｉ
ｎ、Ｔ−剥離）であった。
〔効　果〕
以上のように、この発明の熱融着方法は、従来のように
積層した合成樹脂フィルム上から加熱して、合成樹脂フ
ィルムを金属帯材に融着する方法に比べ、誘導加熱装置
において加熱が金属帯材内部から起って合成樹脂フィル
ムと金属帯Ｈの界面で樹脂が溶融し、合成樹脂フィルム
が金属帯材に融着するというものであるから、以下に列
挙するような効果を奏する。
■　加熱が金属帯絹門部からおこるから加熱温度が１２
０〜１７０℃と低く、樹脂の酸化が極度に減少されるた
め得られた積層品の同種樹脂への熱融着強度が第１表に
示す如く一段と向上すること、 ■　■と同じ理由から樹脂の酸化臭が著しく減少するこ
と。
■　従来法では不可能であった金属帯材への合成樹脂フ
ィルムの両面同時熱融着積層品が得られること。
■　誘導加熱装置によって金属帯材か瞬時に目的の温度
に達するので加熱ゾーンが非常に短いからこの発明の方
法を実施する融着設備のスペースが少（て良いこと。
■　誘導加熱法であるので熱効率が良いこと。
■　金属帯材と合成樹脂フィルムとを、電磁誘導コイル
内を通過させることにより、金属帯材の両面に電磁誘導
コイルが位置して磁束が金属帯材面に対して垂直の方向
に透過するので、渦電流が金属帯材の全中に亘って流れ
、金属帯材を均一に加熱しやすい。
